Previously the richtext editor introduced the loss of the collision
avoidance feature.

  * Upgrade to Redactor 9.1.7
  * Use a (x) icon from font-awesome for the dialog

Since the ticket thread is nested in a div now (required for inline videos
to be displayed correctly), the image hover caused the images to be shown at
the end of the thread entry body rather that its original location.

Fixes #64

Fixes #65

  * Dialogs are scrollable if too big
  * Placement does not respect scroll position now (fixed position)

Fixes #834 (again)

PHP can't discern the difference between d/m/Y and m/d/Y when just the date
is submitted to strtotime(). Unfortunately, strptime() is not available
until PHP 5.1.0. This patch forces datepickers to change their values to
YYYY-MM-DD upon submission to disambiguate parsing issues.

Fixes #832

Previously the American date format (m/d/Y) was used exclusively for
formatting dates in the datepicker widget. This patch enables the widget to
be formatted based on the format set in the admin panel.

Fixes #829

This means that drive-by mouse hovers, where the user likely did not intend
for the hover to actually popup the banner with the filename and download
button, do not trigger the popup. This patch changes the popup effect so
that it requires a 500ms hover before the popup is shown.

*This is a major redesign / rework of the osTicket base*

This patch drops the concept of static ticket metadata and allows for an
admin-configurable arbitrary data that is attachable to tickets

The system is architected such that the base osTicket install now comes with
a "default" form that has fields for subject, name, email, and phone number.
This form is editable to allow for the addition of arbitrary other fields;
however, the basic fields must remain in order to be associated with a
help-topic and attached to a ticket.

This concept can be expanded to allow for arbitrary data associated with
registered clients or ticket thread items.

Forms are comprised of sections. Sections have a title and instructions
properties and a list of fields. Fields have various implementations to
represent different data such as text, long answer, phone number, datetime,
yes/no, and selections, and are configurable to define the look and feel and
interpretation of the respective form field.

Dropdown lists are represented as "Dynamic Lists", which are
admin-configurable lists of items. Dropdowns can be optionally represented
as Bootstrap typeahead fields.

This also adds the start of a simple ORM which will hopefully be expanded in
the future to support multiple database platforms. Currently, only MySQL is
implemented.

Process inline attachments in thread entry and support inline images in
piped emails

Support inline images across the system, with draft support

Migrate to a single attachment table
    That way we don't need a new table for everything we need to attach an
    inline image to (like a signature, for instance)

Add richtext support for internal notes

Implement images on site pages

* Image paste in Redactor
* Make non-local images optional
* Placeholder for non-local images
* Fix local image download hover
* Don't re-attach inline images

The client and scp config ajax request only contain the settings for the
multi-file upload widget. So it doesn't need to be fetched unless the widget
exists on the page

Allows direct editing of XHTML code in the nicEdit pane

Remove default max limit - no size limit is assumed.

Remove ticket.min.js (users can minimize/compress files on thier own)

Add overlay + please wait spinner on form submit

Autosubmit form on load - refresh is called on submit giving it form object
Validate start/stop timeframe in the backend

Remove obsolete functions

Impove row highlighter on table listing.
